To address this gap, investigators propose using Gamma Entrainment Using Sensory Stimulation (GENUS), a novel, home-based treatment involving synchronized 40 Hz light-and-sound stimulation aimed at improving neural synchrony, cognition, and SZ symptoms. This innovative approach leverages advanced neurostimulation, biological, and neuroimaging methods to directly target gamma dysfunction, fulfilling an urgent need for effective and accessible at-home therapies.\n\nThe goal of this clinical trial is to learn about the safety and feasibility of gamma stimulation using light and sound. It will also learn if gamma stimulation using light and sound works to treat clinical symptoms and cognitive impairments in schizophrenia. The main questions it aims to answer are:\n\n1. Is gamma stimulation safe for patients with schizophrenia spectrum disorders?\n2. Does gamma stimulation alleviate clinical symptoms and cognitive impairments in schizophrenia patients?\n\nParticipants will:\n\n1. Have an acute 1-hour stimulation at MIT.\n2. Come for a one-day visit to MIT for stimulation, neuroimaging, clinical, and cognitive evaluations.",[89],"Schizophrenia Spectrum Disorders",[91,92,93,23],"schizophrenia","sensory stimulation","gamma stimulation","NOT_YET_RECRUITING","2026-01-23",{"date":97,"type":98},"2026-01-26","ACTUAL",{"date":100,"type":83},"2026-04",{"date":102,"type":83},"2027-04",{"name":5,"class":6},1]
